摘要： The invention relates to a bending angle measuring device (1) comprising an illumination device (2) and an image capturing device (3), said illumination device (2) comprises a light source (4) and the image capturing device (3) comprises an image sensor (5). A beam path (8) is formed between the light source (4) and the image sensor (5), along which beam path a light bundle emitted by the light source (4) travels over a workpiece (9) which is to be bent, to the image sensor (5). Said illumination device (2) also comprises a first beam former (12) which is arranged in the beam path (8), and the image capturing device (3) comprises a second beam former (14) which is arranged in the beam path (8). Said image sensor (5) is connected to an evaluation and analysis module (17). A light pulse (19) is emitted by the illumination device (2) at an output time point t_0, said light pulse comprising a light phase of the duration T_z and the image sensor (5) detects an image of the workpiece (9) at a detection time point t_c, the single image acquisition time being shorter than or equal to twice that of the duration T_z.
